VAPOBIZING ATTACHMENT FOR EXPLOSIVE-ENGINES.

Specification of Letters Patent.

Patented May 14, 1918 Application filed March 25, 1916. Serial No. 86,747.

Hazlehurst, in the county of Copiah and' State of Mississippi, have invented certain new and useful Improvements in Vaporizing Attachments for Explosive-Engines, of which the following is a specification.

The present invention comprises new and useful means for facilitating the thorough vaporization of hydrocarbon fuel such was commonly employed in connection with the operation of internal combustion engines.

A primary'object of this invention has been to design an attachment susceptible of being. employed in connection with ordmary types of explosive engines, and preferably utilized auxiliary to the customary carbureting means used, whereby the explosive mixture after it has left the carbureter is caused to pass to a preheating chamber. In the preheating chamber the more or less effectively carbureted mixture is subjectedto the action of peculiarly arranged and formed heating tubes or members by which the mixture is effectively broken up and vaporized, whereupon it is permitte to pass to the cylinder or cylinders of the motor to be exploded in the customary manner.

Still another object of the invention has been the provision of a means such as the attachment above generally described which does not require any material modification in the usual engine parts in order that the invention may be adapted to the latter, the attachment comprising various chambers, tubular or pipe connections adapted to be readily combined with the usual carbureter, intake manifold and exhaust pipe parts, all in a manner which will appear very fully upon reference to the following detail description and to the accompanying drawings, in which Figure 1 is a view partly in elevation and partly in section showing the invention applied to the intake and exhaust manifold of an explosive engine and in connection with the carbureter for the latter.

Fig. 5 is a section taken about on the line 55 of Fig. 1.

Fig. 6 is a sectional view of a modified embodiment of the invention.

Fig. 7 is a sectional view of another modification of the invention.

Referring particularly to Figs. 1 to 5 inclusive of the drawings wherein a preferred form of my invention is illustrated,

A denotes the ordinary intake manifold of an explosive engine and B the exhaustmanifold, the former being disposed adjacent to a carburetor C of conventional construction and connected therewith by peculiar means to be described. The exhaust manifold B is provided with openings 1 and- 2 establishing communication between the same and the preheating chamber 3. The preheating chamber 3 is seen best in Figs. 2 and 3, being formed at its bottom with the longitudinal seat which partially receives the intake manifold, the parts B and 3 being positively connected by couplings 4. A suitable exhaust outlet pipe 5 extends from the preheating chamber 3 at a point approximately centrally of its ends. I

Arranged within the preheating chamber 3 is the vaporizing pipe or passage 6 the same consisting of a rebent pipe having branches 7 and -8 leading laterally and downwardly from the chamber 3, the lower terminals of the branches of the vaporizing plpe being connected in any suitable manner with the separating chamber 9 which latter consists of'a somewhat rectangular or boxlike body formed with a horizontal partition 10. To the under side of the separator 9 is attached the pipe leading from the carbureter C, and to the upper side of the chamber 9 is attached the lower end of the intake manifold A. Any suitable means such as the flanges 11 and screws 12 are utilized to connect the parts just last mentioned. The purpose 0 the partition 10*is to divide the separator 9 into an inflow chamber 9 and an outflow chamber 9 to A properly direct the carbureted fuel passing into the chamber 9 from the carburetor C.

to cause said fuel to pass upward through the branch pipe 7 into the vaporizing-pipe or passage 6 from which the fuel in thoroughly vaporized heated condition is caused to pass or return to the separator 9 at the outflow chamber 9 with which chamber the per tubes passing through the pipe 6 and the ends of which are swaged or clenched to establish the requisite air-tight connecticn between the baffles andthe pipe 6. The bafiies 1 are preferably disposed in staggered relation to insure the impingement thereagainst of the fuel constituents entering the pipe 6, and the exhaust gases pass through said baflies.

The operation of the invention as above described will be evident but may be saidto consist in the passage of the carbureted fuel through the chamber 9", branch pipe 7, into the vaporizing pipe 6 located in the preheating chamber 3, from which the thoroughly vaporized mixture in gaseous form is led through the pipe 8 to the outflow chamber 9" of the separator 9 and from. thence to the intake manifold A to be supplied to the cylinders of the engine in the customary manner.

In Fig. 6 a modification of the invention is disclosed wherein the inflow chamber 9 of the separator is connected witha branch pipe 7' leading to one end of the vaporizing pipe 6', the latter being mounted in the preheating ch er 3'. The vaporizing pipe 6 in t 's instance is a straight pipe supplied wit the tubular bafiies of the desicription previously set forth, said pipe being connected with the branch pipe 7 at one end, and the opposite end connected with the branch pipe 8, the latter leading to the outflow chamber 9" of the separator. In this instance the intake manifold is connected at its lower end with the outflow ea er? of the exhaust pipe connection 14. The lower portion of the intake manifold A is, provided with the horizontal tubular bailies for breaking up the carbureted fuel for the purposes of thorough vaporization, after the manner of the formation of the parts 6 and 6 previously described. The exhaust outlet .pipe is shown at 15 as leading from the lower portion of the chamber 3". For certain types of motors, and under certain conditions of service operation, the simple embodiment of the invention just described will afiord a far more economical usage of fuel than obtainable incident to the employment of a carbureter alone.

In relation to the tubular baflles used in each adaptation of my invention above described, it is to be noted that these baflles while disposed in parallel planes pass transverselythrough the vaporizing pipe so as to intersect, practically speaking, the axis of said pipe, by which is meant the longitudinal axial center of the pipe. Furthermore, these baflles may not only be characterized as staggered as previously mentioned, but are disposed at angles to one another so that from the standpoint ofefiiciency of the breaking up action of the baflles in respect to the ingredients of the explosive fuel, a most advantageous structure is obtained.

Having thus described the invention, what is claimed is: v
